Definitions

  • the present invention relates to an easily installed window or door frame, primarily intended for trailer bodies but which can also be used for other purposes.
  • Trailer bodies are built essentially by hand. Moreover, they are constructed of a variety of materials, with a variety of insulating materials. Consequently, the wall thickness may vary substantially in different models of trailers.
  • the window unit is one of the parts falling in this category.
  • the window itself does not present any real difficulty in manufacture, and, as a rule, is made of some appropriate plastic, e.g. acrylic plastic.
  • Such windows are, moreover, already being mass produced by specialized manufacturers.
  • the purpose of the present invention is to provide a frame which can easily be installed by one person, who can insert the frame entirely from the inside of the trailer body, despite the presence of the window pane.
  • the frame of the invention does not require any pre-fixing by means of wedges or the like, and there are comparatively liberal requirements for the tolerances of the wall opening. A certain amount of play is permissible between the outer surface of the frame and the inner surface of the support wall.
  • the main part of the frame of the invention consists of a main frame constructed of a single part of formed by joining several separated parts.
  • the main frame should be constructed of a material which is not cold-conducting.
  • Plastic material with a cellular structure has an insulating effect, and is therefore particularly suitable.
  • Extrusion or injection moulding of some appropriate plastic material, e.g. polyurethane also makes it possible to directly attach to the frame a variety of elements such as fasteners for window hinges, stops for lock handles, drip and seal grooves or mouldings and reinforced fastening points for positioning the clamping strips during installation of the frame.
  • the frame according to the invention comprises a main frame constructed from pairs of opposite transversal and longitudinal frame parts.
  • the parts of the frame form right angles to each other.
  • This main frame is inserted into an opening in the wall in such a way that the outer edge surfaces slope away from each other and are joined to the inner edge surfaces of the walls which face each other. Between these edge surfaces, a certain degree of play is tolerated. Play of up to 5-10 mm is possible, even if play of more than 5 mm is unsuitable from the point of view of insulation. The only critical factor is that the opening in the wall is not too small for the frame.
  • the acrylic plastic windows themselves should be formed with rounded corners. Casements are not needed for double acrylic plastic windows, but the actual frame should be adaptable to fit in wall openings with sharp corners.
  • the frame of the invention includes an outer flange which is clamped against the wall during installation of the frame.
  • This flange is attached to the outer edge surfaces of the frame and is positioned at a substantially right angle thereto.
  • the flange contacts the part of the outer wall which is adjacent the window opening.
  • the frame is thereafter secured in place by clamping strips positioned to contact both the inside of the frame and the inner wall adjacent the window opening.
  • the clamping strip of the invention consists of a shallow U-shaped clamping strip, the body of which is rather wide compared with the height of its two upwardly extending flanges.
  • a characteristic feature of the invention is that one of these two flanges (which can be of different lengths) contacts and is aligned with an adjacent part of the frame, while the other flange contacts the wall adjacent the window opening.
  • the clamping strip is connected with the frame in such a way that the cross-section of the clamping strip can be positioned obliquely in relation to the main plane of the frame.
  • the same frame assembly can be installed in different wall openings of varying thicknesses. If the longer flange of the clamping strip is in contact with the frame, the frame will fit in wall openings which are thicker than the frame, while if the shorter flange of the clamping strip is in contact with the frame, the frame will fit into wall openings thinner than the frame.
  • the clamping strip can be set at an oblique angle and retained in position by fastening screws connecting the clamping means to respective parts of the frame. This oblique setting compensates for variations in wall thickness. If the wall and frame should be of the same thickness, a U-shaped clamping strip with substantially identical flanges can be used.
  • One side of the frame is provided with guide grooves for engagement with the flanges of the clamping strip, while the flange attached to the frame and abutting the wall is provided with a groove for inserting sealing paste.
  • the frame of the invention which can also be used for light doors, may be supplied to the trailer manufacturer complete with inserted windows or doors. Thereafter, the frame can be installed without removal of the window or door.
  • FIG. 1 is an installed window frame of the invention which contains a double acrylic plastic window
  • FIG. 2 is a rear view of the frame of FIG. 1 without the window;
  • FIG. 3 is a detailed view of a frame installed in a wall which is thinner than the frame;
  • FIG. 4 is a detailed view of a frame installed in a wall which is thicker than the frame.
  • the frame 1 cna be divided into pairs of parallel frame parts 2-5. Excluding the folded edge 6, which supports and positions the window with respect to the frame, the parts of the frame have a substantially L-shaped cross-section.
  • the lower leg of the L-shaped cross-section consists of an edge flange 7, with a portion 8 which, when the frame is installed, is facing inwardly toward the outer wall and is provided with a groove 9 for sealing paste.
  • groove 9 is filled with a bead of sealing paste. Connected with groove 9 is a further narrow groove 10. When the frame is pressed into place, the excess sealing agent is pressed into groove 10, instead of being pressed outside the frame.
  • FIG. 3 a certain amount of play exists between side 11 of the frame and sides 12 and 13 of the wall opening.
  • the wall 14 is thinner than the frame, and in FIG. 4 the wall 15 is thicker than the frame.
  • the double-walled acrylic plastic window 16 is joined to the frame via a sealing strip 17.
  • This sealing strip which is made of a special rubber profile, is postioned in a groove 18 in the frame.
  • the frame itself may be made of injection moulded polyurethane.
  • the clamping strips 22 may have extruded aluminum profiles. Their length corresponds to the length of the parts of the frame. Clamping strips 22 are provided with oval holes 23 for screws 21 which allow the window locks of the clamping strip to be obliquely set.
  • the clamping strips 22 of the present invention have the form of a shallow U-beam, with a central body which is wider than the lengths of the flanges 24, 25 of the U-beam.
  • Flanges 24 and 25 may be formed of different lengths. As shown in FIGS. 3 and 4, their front surfaces can be ground to form a sharp edge which prevents slipping between frame 1 and clamping strip 22 or between clamping strip 22 and wall 14, 15.
  • clamping angle can be varied so that frame 1 will fit walls which are either thinner or thicker than the frame.
  • the oblique setting of clamping strips 22 as shown in FIG. 4 further increases the flexibility of the frame assembly.
  • the combination of polyurethane and metal clamping strips provides a very rigid unit, although neither frame 1 nor clamping strip 22 alone exhibits much rigidity.
  • frame 1 In order to improve the contact between clamping strip 22 and frame 1, and to facilitate installation, frame 1 has been provided with a guide groove 26.
  • FIG. 1 the window locks 27 and 28 as well as the hinge strip 30 are shown.
